Summary
Instrument failure during arthroscopic surgery is common, particularly with forceps. This analysis of nearly 1000 operations highlights high breakage rates for grasping and basket forceps, sometimes requiring further procedures.
Area of Science:
- Orthopedic Surgery
- Surgical Instrumentation
Background:
- Routine arthroscopic operations rely heavily on specialized surgical instruments.
- Understanding instrument performance and failure rates is crucial for patient safety and procedural efficiency.
Purpose of the Study:
- To analyze the usage patterns and breakage rates of operating instruments in routine arthroscopic procedures.
- To identify specific instruments with high failure rates and assess the impact of these failures.
Main Methods:
- Retrospective analysis of 2397 arthroscopies, focusing on 986 operations.
- Detailed recording of instrument combinations used, with meniscectomy as the most frequent procedure.
- Calculation of instrument breakage rates per 100 operations for various instruments, including forceps and telescopes.
Main Results:
- The most common instrument set included a knife, 4 mm grasper, 3-4 mm basket forceps, and suction device (53% of cases).
- High breakage rates were observed for straight basket forceps (2/100 operations) and grasping forceps (3.6/100 operations).
- Telescope replacement rates were 0.8/100 for 30-degree and 0.2/100 for 70-degree scopes.
Conclusions:
- Instrument failure, especially of forceps, is a significant concern in arthroscopic surgery.
- The high breakage rates necessitate attention to instrument quality and surgical technique to minimize complications and the need for revision procedures.
